T0 alli/whom it may concern:

Be it known that I," NICOLAS OLivIER, a

citizen or the French Republic, anty a resident of Lyon, France, haveinvente certain new and useful Improvements in Parallel Vises, of whichthe following is a specication.

The present invention relates to a parallel vise which can be rapidlymoved andv held in any desired position according'- to the nature of thework to be eiected.

The accompanying drawings show by way of example one form of viseconstructed in accordance with this invention.

Figure l is a front elevation.

Fig. 2 is a side view.

Fig. 3 is a plan.

Fig. 4 is a transverse section on line 4 4.

Fig. 5 is a longitudinal section on line 5 5.

Fig. 6 shows in detail a front elevation and plan respectively of theengaging nut of the movable jaw of the vise.

Fig. 7 is a detail view of the cam for bringing the nut into engagementwith the actuating screw.

A plate a is ailiXed by screws or bolts b on a bench c or on to thetable of a machine tool. The plate a is provided with an oval aperturethe sides a1 of which are inclined and with a diametrical groove a2 inwhich a long key d can move. The key d is recessed at il and terminatesin a screwed portion Z2 to receive the screwed head e1 of an actuatinglever e.

A truncated conical projection f1 of a support f projects into thecentral aperture of the plate a and rests on the recessed portion d1 ofthe key el. The support f is bored out to form a universal bearing forthe trunnion g1 of one of the jaws g of the vise, which is preventedfrom leaving its bearing by a ring 7L affixed to its end by screws z'.

The trunnion g1 is hollowl to receive a sliding member y'l forming partof the jaw y' of the vise. The slidingv member jl ispreferably hollow toreceive a screw 7c passing longitudinally therethrough.

The screw lo is carried by the bearings jg, ja and is formed at one endwith a head 761 through which passes the level Z by which it isoperated. Two nuts m hold the screw 7c in position in the bearings y'2,js in which it can freely rotate.

The jaw g is provided on its under side with a projection g2 having alarge aperture in which a block n, is mounted so as to be capable ofmoving freely therein. The upper part of the block a is formed with ascrew thread to form a nut nl for the screw 7c (Fig. 6). The .block aisl also formed with an opening n.2 to receive a cam 0 one of thetrunni'ons 01A of which is situated in a recess formed in the projectiong2 and the other trunnion o2 rotates in a sleeve screwed into anaperture on the other face of the said projection. The end of the trunnion o2 is rectangular and the operating lever g which is provided witha handle g1 is aHiXed thereto by a screw.

The su port f is formed infits lower part with a slit f2 and a holepasses through the two parts, the hole in the part below the slit f2being screwed to receive a rod r screwed at its end r1. The upper end ofthe rod 1 is formed with a head r2 which engages a boss s on the supportf. A pin r3 is provided for operating the rod 1'.

The working of the vise is as follows:

To open and close the vise quickly the lever g is moved to the positionat which the cam o causes the block n to move downward (position shown.in dotted lines in Fig. 5). The nut n1 is then disengaged from the screw7c and the jaw with its slide member jl can then be moved backward andforward as desired without operating the screw c.

To open and close the vise by means of the screw 7c the lever g isturned into the position at which the cam 0 moves the block n intoengagement with the screw 7c (position shown. in full lines in Fig. 5)and the vise then operates as an ordinary parallel vise.

To vary the rotary position of the vise the lever e is turned into theposition to release the key d. The truncated conical portion f1 of thesupport f can then be rotated in its support and the whole of the viseturned about the plate a into the position, for example shown in dottedlines in Fig. 3. The vise is again locked into the desired position byturning the lever e in the reverse direction and as the head e1 forms anut for theV screwed end d? Yof the key d the latter is displaced tolock the truncated conical portion f1 of the support f against the platea.

Finally the aws can be pivoted about the screw 7c taken. as its axis. Toei'ect this the rod r is rotated so that its screwed end r1 produces aslight loosening of the two parts of the support f separated by the slit2. The trunnion g1 can then rotate in the earing formed by the support fto the p0- sition for example shown in dotted lines in Fig. l. It islocked in the desired position by the rotation of the rod 7" in theopposite direction which Causes the tighten-v ing together of the tWoparts of the support j separated by the slit f2.

The movable sliding member y' may be of circular or rectangular section.Furthermore the arrangements Which have been described are not onlyapplicable to a bench vise but to vises of all types employed forholding articles on machine tools.

What I claim as my invention isz- A quick action parallel vise capableof being rotated in the plane of its support and in a planeperpendicular thereto comprising a plate formed at its center with anaperture the edges of Which are inclined, a support with a truncatedconical base engaging in the said aperture, a sliding key on Which saidbase rests, said key serving to lock the said base to the support andmeans for moving the key for locking and releasing the support to permitof the rotation thereof substantially as described.

In Witness whereof I aiX my signature.
